Description

Technical Field

[0001] The invention relates to a signal and energy synchronous transmission device, in particular to a single-coil frequency modulation type magnetic coupling signal and energy synchronous transmission device. Background Art

[0002] With the development of the Internet of Things, some intelligent systems need to be powered in real time when they are running, and also need to realize real-time two-way transmission of signals between external controllers and such intelligent systems to realize intelligent control. For example, an intelligent system used to control the temperature of a fish tank in cooperation with a thermostat is installed on the fish tank. While powering the intelligent system, the thermostat not only needs to obtain the temperature of the fish tank, but also needs to control the intelligent system according to the temperature of the fish tank, that is, the thermostat needs to send a temperature acquisition control signal to the intelligent system. After receiving the temperature acquisition control signal, the intelligent system needs to send the detected fish tank temperature (corresponding to the operating state) to the thermostat. The thermostat generates a temperature adjustment control signal based on the received fish tank temperature to control the intelligent system, adjust the temperature of the fish tank or maintain the temperature of the fish tank, that is, two-way transmission of signals needs to be realized between the thermostat and the intelligent system.

[0003] At present, the power supply of such intelligent systems and the realization of bidirectional transmission of signals between such intelligent systems and external controllers are completed by setting up a full-duplex power line communication device at such intelligent systems. On the one hand, the existing full-duplex power line communication device can transmit energy to such intelligent systems to power all energy-consuming loads inside such intelligent systems. On the other hand, it can receive the control signal transmitted by the external controller and output it to such intelligent systems after demodulation, so that the central processor of such intelligent systems can change the operating state of such intelligent systems and obtain the operating state of such intelligent systems and output it to the external controller. However, the existing full-duplex power line communication device uses a wired method to complete the above functions, which makes the lines of such intelligent systems complex and difficult to install and maintain. At the same time, when the external controller transmits signals to the intelligent system, a signal transmission module must be set in the external controller at the beginning of the design, which further increases the difficulties faced above. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a single-coil frequency-modulated magnetically coupled signal and energy synchronous transmission device which can not only simplify the circuit of the intelligent system and reduce the difficulty of its installation and maintenance, but also enable the external controller to omit the signal transmission module, thereby eliminating the need for an additional design of a signal transmission module, when used for the power supply of the intelligent system and the bidirectional transmission of signals between an external controller and such intelligent system.
